Research Fields

My research interests center around the study of large-scale structure of the Universe, and galaxy clustering
and evolution. I am currently analysing and modeling radio galaxy correlations to study galaxy-biasing,
active galactic nucleus (AGN) radio activity, and large scale anisotropy anomalies. I have also been working
on other topics i.e. structure formation, local universe constrained simulations, intergalactic magnetic field
modeling, and astrophysical particles (e.g. Axions) and their implications from cosmological observations.
